Abstract

Embodiments of the present invention provide a data packet transmission method and system, a sending end device, and a receiving end device. The method includes: the sending end determines the QoS requirement information of the service data according to the content or type of the service data; the QoS requirement information includes at least one of transmission delay priority level, transmission reliability priority level, packet loss indication and emergency indication; The sending end carries the QoS requirement information in the data packet corresponding to the service data; and sends the data packet carrying the QoS requirement information to the receiving end, so that the receiving end can schedule and process the data packet according to the QoS requirement information. The technical solution of the embodiment of the present invention can overcome the defect that all data packets are processed in a centralized manner in the prior art, resulting in low processing efficiency of the data packets. By scheduling and processing the received data packets according to the quality of service requirement information, it is possible to Effectively improve the processing efficiency of data packets.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a data packet transmission method and system, a sending end device, and a receiving end device. Background technique [0002] In the evolved packet system (Evolved Packet System; EPS), the bearer (Bearer) is used to transmit the service data of the user equipment (User Equipment; UE). According to the different networks through which the service data in the bearer passes, the Bearer includes the core network (Core Network; CN) bearer and radio access network (Radio Access Network; RAN) bearer. [0003] In an existing wireless network, for a specific service, RAN bearer can adopt two transmission modes at the radio link control (RadioLink Control; RLC) layer: Acknowledged Mode (Acknowledged Mode; AM) and Unacknowledged Mode (Unacknowledged Mode) -acknowledged mode; UM). In AM mode, the RLC layer uses the Automatic Repeat-reQuest (ARQ) mechanis...
